For landowners
What could your land return?
Under a joint-development agreement you keep the land and receive a share of the
finished building. Enter your plot size to see the rough shape of that deal — buildable
area, your share of it, and what that share might be worth.
Before you rely on this
These are Bhabon Builders' working assumptions, not RAJUK figures. The Detailed
Area Plan sets FAR by road width, building type, zone and area block — not by
plot size alone — so the approved figure can differ in either direction. Check
your plot on the
RAJUK master plan portal .
Buildable area here is gross . Lifts, stairs, corridors and
parking come out of it before anything is saleable.
The split is shown as a range because it is negotiated per plot — anywhere from
50:50 to 60:40 in the developer's favour. Assume the lower end until a
feasibility study says otherwise. The rate per square foot is indicative too,
and moves with the market and the finish specification.
Nothing is final until soil testing, any road surrender, and formal RAJUK
approval. A real feasibility study can move every number on this page.
How the estimate is worked out
Plot area is your katha figure times 720 square feet. That is multiplied by the FAR
band for the plot size to give the total buildable area; your share is a percentage of
it, valued at an assumed market rate per square foot.
The FAR bands this page uses
Plot size FAR
Under 3 katha 3.15
3 to 5 katha 3.50
Above 5 katha 4.00
A plot of exactly 3 katha takes the middle band; exactly 5 katha stays in it.
The split itself is shown as a range, not a single number, because that is what it is:
it runs from 50:50 to 60:40 in the developer's favour — so 40% to 50%
of the building comes to you — and where a particular plot lands is settled in the
agreement after the feasibility study.
The FAQ explains what moves it.
Market rate assumed at ৳ 8,500 per square foot, and the unit count assumes an average
unit of 1,250 square feet.
